by ADMIN 86 views

Introduction

VirtualBox is a popular virtualization software that allows users to run multiple operating systems on a single machine. However, like any other software, it is not immune to issues and bugs. One common problem that users face is the loss of Internet access in the guest operating system, even when the host machine has a stable connection. In this article, we will explore the possible causes of this issue and provide some troubleshooting steps to help you resolve the problem.

Understanding the Setup

Before we dive into the possible causes, let's take a look at the setup you described:

  • Host machine: Windows 11 24H2 Pro
  • VirtualBox version: 7.1.4 r165100 (Qt6.5.3)
  • Guest operating system: Windows 10 21H2 Pro

It's essential to note that the version of VirtualBox and the guest operating system can play a significant role in determining the cause of the issue.

Possible Causes of Internet Loss in Guest OS

There are several reasons why your Windows 10 guest running on VirtualBox might lose Internet access. Here are some possible causes:

1. VirtualBox Network Settings

The first thing to check is the network settings in VirtualBox. Make sure that the network adapter is properly configured and that the guest operating system is set to use the correct network adapter. You can do this by following these steps:

  • Open VirtualBox and select the guest operating system.
  • Click on the "Settings" button.
  • Go to the "Network" section.
  • Ensure that the "Attached to" option is set to "Bridged Adapter" or "NAT Network".
  • Verify that the "Adapter Type" is set to "Intel PRO/1000 MT" or "Intel PRO/1000 T".

2. Network Adapter Configuration

The network adapter configuration in the guest operating system can also cause issues. Make sure that the network adapter is properly configured and that the IP address is set correctly. You can do this by following these steps:

  • Open the Network and Sharing Center in the guest operating system.
  • Click on the "Change adapter settings" link.
  • Right-click on the network adapter and select "Properties".
  • Ensure that the "Internet Protocol Version 4 (TCP/IPv4)" option is enabled.
  • Verify that the IP address is set correctly.

3. VirtualBox Guest Additions

The VirtualBox Guest Additions are a set of drivers and utilities that are installed in the guest operating system to improve performance and functionality. However, sometimes these additions can cause issues with the network connection. Make sure that the Guest Additions are properly installed and updated. You can do this by following these steps:

  • Open the VirtualBox Guest Additions Control Center in the guest operating system.
  • Click on the "Update" button.
  • Verify that the Guest Additions are properly installed and updated.

4. VirtualBox Version

As mentioned earlier, the version of VirtualBox can play a significant role in determining the cause of the issue. Make sure that you are running the latest version of VirtualBox. You can check for updates by following these steps:

  • Open VirtualBox and select the guest operating system.
  • Click on the "Help" menu.
  • Select "Check for Updates".
  • Verify that the latest version of VirtualBox is installed.

5. Guest Operating System

The guest operating system can also cause issues with the network connection. Make sure that the guest operating system is properly configured and that the network adapter is set correctly. You can do this by following these steps:

  • Open the Network and Sharing Center in the guest operating system.
  • Click on the "Change adapter settings" link.
  • Right-click on the network adapter and select "Properties".
  • Ensure that the "Internet Protocol Version 4 (TCP/IPv4)" option is enabled.
  • Verify that the IP address is set correctly.

6. Firewall Settings

The firewall settings in the guest operating system can also cause issues with the network connection. Make sure that the firewall is properly configured and that the network adapter is set correctly. You can do this by following these steps:

  • Open the Windows Defender Firewall in the guest operating system.
  • Click on the "Advanced Settings" link.
  • Ensure that the "Inbound Rules" and "Outbound Rules" options are enabled.
  • Verify that the network adapter is set correctly.

7. VirtualBox Network Bridge

The VirtualBox network bridge can also cause issues with the network connection. Make sure that the network bridge is properly configured and that the network adapter is set correctly. You can do this by following these steps:

  • Open VirtualBox and select the guest operating system.
  • Click on the "Settings" button.
  • Go to the "Network" section.
  • Ensure that the "Attached to" option is set to "Bridged Adapter".
  • Verify that the network adapter is set correctly.

Troubleshooting Steps

If you have tried the above steps and still experience issues with the network connection, here are some additional troubleshooting steps you can try:

1. Disable the VirtualBox Guest Additions

Disable the VirtualBox Guest Additions and see if the issue persists. You can do this by following these steps:

  • Open the VirtualBox Guest Additions Control Center in the guest operating system.
  • Click on the "Disable" button.
  • Verify that the Guest Additions are properly disabled.
